Bokeh is a subjective judgment of quality about the objectively out-of-focus areas of an image. Aspherical elements can also influence the rendering of out-of-focus regions by introducing what is known as “onion-ring” bokeh. This is the first time I've seen anything in print referring to it.

This effect appears as a texture of rings on the bokeh discs and is caused by very slight defects in the lens surface. The longitudinal CA will produce a color tint on the entire disc. At wide apertures, light is entering the aperture diaphragm from a wide range of angles. A blurry background directs the viewer’s attention to the depicted subject. As we covered above, the aperture, focal length, and sensor size all affect the depth of field. There is no requirement for there to be any specular highlights in the image for there to be bokeh.

This, in turn, means there’s a very large depth of field, and thus, no bokeh. If you read my article on star effects, you know that diffraction caused by the shape of the aperture diaphragm will determine the shape of light passing through said diaphragm.
